| CVE-2019-18933 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| In Zulip Server versions from 1.7.0 to before 2.0.7, a bug in the new user signup process meant that users who registered their account using social authentication (e.g., GitHub or Google SSO) in an organization that also allows password authentication could have their personal API key stolen by an unprivileged attacker, allowing nearly full access to the user's account. | |||||
| CVE-2019-16216 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 3.5 LOW | 5.4 MEDIUM |
| Zulip server before 2.0.5 incompletely validated the MIME types of uploaded files. A user who is logged into the server could upload files of certain types to mount a stored cross-site scripting attack on other logged-in users. On a Zulip server using the default local uploads backend, the attack is only effective against browsers lacking support for Content-Security-Policy such as Internet Explorer 11. On a Zulip server using the S3 uploads backend, the attack is confined to the origin of the configured S3 uploads hostname and cannot reach the Zulip server itself. | |||||
| CVE-2019-16215 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| The Markdown parser in Zulip server before 2.0.5 used a regular expression vulnerable to exponential backtracking. A user who is logged into the server could send a crafted message causing the server to spend an effectively arbitrary amount of CPU time and stall the processing of future messages. | |||||
| CVE-2018-9999 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 3.5 LOW | 5.4 MEDIUM |
| In Zulip Server versions before 1.7.2, there was an XSS issue with user uploads and the (default) LOCAL_UPLOADS_DIR storage backend. | |||||
| CVE-2018-9990 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.3 MEDIUM | 6.1 MEDIUM |
| In Zulip Server versions before 1.7.2, there was an XSS issue with stream names in topic typeahead. | |||||
| CVE-2018-9987 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.3 MEDIUM | 6.1 MEDIUM |
| In Zulip Server versions 1.5.x, 1.6.x, and 1.7.x before 1.7.2, there was an XSS issue with muting notifications. | |||||
| CVE-2018-9986 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.3 MEDIUM | 6.1 MEDIUM |
| In Zulip Server versions before 1.7.2, there were XSS issues with the frontend markdown processor. | |||||
| CVE-2017-0910 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.0 MEDIUM | 8.8 HIGH |
| In Zulip Server before 1.7.1, on a server with multiple realms, a vulnerability in the invitation system lets an authorized user of one realm on the server create a user account on any other realm. | |||||
| CVE-2017-0896 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| Zulip Server 1.5.1 and below suffer from an error in the implementation of the invite_by_admins_only setting in the Zulip group chat application server that allowed an authenticated user to invite other users to join a Zulip organization even if the organization was configured to prevent this. | |||||
| CVE-2017-0881 | 1 Zulip | 1 Zulip Server | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| An error in the implementation of an autosubscribe feature in the check_stream_exists route of the Zulip group chat application server before 1.4.3 allowed an authenticated user to subscribe to a private stream that should have required an invitation from an existing member to join. The issue affects all previously released versions of the Zulip server. | |||||
| CVE-2023-47642 | 1 Zulip | 1 Zulip Server | 2024-02-28 | N/A | 4.3 MEDIUM |
| Zulip is an open-source team collaboration tool. It was discovered by the Zulip development team that active users who had previously been subscribed to a stream incorrectly continued being able to use the Zulip API to access metadata for that stream. As a result, users who had been removed from a stream, but still had an account in the organization, could still view metadata for that stream (including the stream name, description, settings, and an email address used to send emails into the stream via the incoming email integration). This potentially allowed users to see changes to a stream’s metadata after they had lost access to the stream. This vulnerability has been addressed in version 7.5 and all users are advised to upgrade. There are no known workarounds for this issue. | |||||
| CVE-2024-21630 | 1 Zulip | 1 Zulip Server | 2024-02-28 | N/A | 4.3 MEDIUM |
| Zulip is an open-source team collaboration tool. A vulnerability in version 8.0 is similar to CVE-2023-32677, but applies to multi-use invitations, not single-use invitation links as in the prior CVE. Specifically, it applies when the installation has configured non-admins to be able to invite users and create multi-use invitations, and has also configured only admins to be able to invite users to streams. As in CVE-2023-32677, this does not let users invite new users to arbitrary streams, only to streams that the inviter can already see. Version 8.1 fixes this issue. As a workaround, administrators can limit sending of invitations down to users who also have the permission to add users to streams. | |||||
| CVE-2023-32678 | 1 Zulip | 1 Zulip Server | 2024-02-28 | N/A | 6.5 MEDIUM |
| Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat. Users who used to be subscribed to a private stream and have been removed from it since retain the ability to edit messages/topics, move messages to other streams, and delete messages that they used to have access to, if other relevant organization permissions allow these actions. For example, a user may be able to edit or delete their old messages they posted in such a private stream. An administrator will be able to delete old messages (that they had access to) from the private stream. This issue was fixed in Zulip Server version 7.3. | |||||
| CVE-2023-28623 | 1 Zulip | 1 Zulip | 2024-02-28 | N/A | 3.7 LOW |
| Zulip is an open-source team collaboration tool with unique topic-based threading. In the event that 1: `ZulipLDAPAuthBackend` and an external authentication backend (any aside of `ZulipLDAPAuthBackend` and `EmailAuthBackend`) are the only ones enabled in `AUTHENTICATION_BACKENDS` in `/etc/zulip/settings.py` and 2: The organization permissions don't require invitations to join. An attacker can create a new account in the organization with an arbitrary email address in their control that's not in the organization's LDAP directory. The impact is limited to installations which have this specific combination of authentication backends as described above in addition to having `Invitations are required for joining this organization` organization permission disabled. This issue has been addressed in version 6.2. Users are advised to upgrade. Users unable to upgrade may enable the `Invitations are required for joining this organization` organization permission to prevent this issue. | |||||
| CVE-2023-32677 | 1 Zulip | 1 Zulip | 2024-02-28 | N/A | 3.1 LOW |
| Zulip is an open-source team collaboration tool with unique topic-based threading. Zulip administrators can configure Zulip to limit who can add users to streams, and separately to limit who can invite users to the organization. In Zulip Server 6.1 and below, the UI which allows a user to invite a new user also allows them to set the streams that the new user is invited to -- even if the inviting user would not have permissions to add an existing user to streams. While such a configuration is likely rare in practice, the behavior does violate security-related controls. This does not let a user invite new users to streams they cannot see, or would not be able to add users to if they had that general permission. This issue has been addressed in version 6.2. Users are advised to upgrade. Users unable to upgrade may limit sending of invitations down to users who also have the permission to add users to streams. | |||||
| CVE-2023-33186 | 1 Zulip | 1 Zulip Server | 2024-02-28 | N/A | 6.1 MEDIUM |
| Zulip is an open-source team collaboration tool with unique topic-based threading that combines the best of email and chat to make remote work productive and delightful. The main development branch of Zulip Server from May 2, 2023 and later, including beta versions 7.0-beta1 and 7.0-beta2, is vulnerable to a cross-site scripting vulnerability in tooltips on the message feed. An attacker who can send messages could maliciously craft a topic for the message, such that a victim who hovers the tooltip for that topic in their message feed triggers execution of JavaScript code controlled by the attacker. | |||||
| CVE-2023-22735 | 1 Zulip | 1 Zulip Server | 2024-02-28 | N/A | 4.6 MEDIUM |
| Zulip is an open-source team collaboration tool. In versions of zulip prior to commit `2f6c5a8` but after commit `04cf68b` users could upload files with arbitrary `Content-Type` which would be served from the Zulip hostname with `Content-Disposition: inline` and no `Content-Security-Policy` header, allowing them to trick other users into executing arbitrary Javascript in the context of the Zulip application. Among other things, this enables session theft. Only deployments which use the S3 storage (not the local-disk storage) are affected, and only deployments which deployed commit 04cf68b45ebb5c03247a0d6453e35ffc175d55da, which has only been in `main`, not any numbered release. Users affected should upgrade from main again to deploy this fix. Switching from S3 storage to the local-disk storage would nominally mitigate this, but is likely more involved than upgrading to the latest `main` which addresses the issue. | |||||
| CVE-2022-36048 | 1 Zulip | 1 Zulip | 2024-02-28 | N/A | 4.3 MEDIUM |
| Zulip is an open-source team collaboration tool with topic-based threading that combines email and chat. When displaying messages with embedded remote images, Zulip normally loads the image preview via a go-camo proxy server. However, an attacker who can send messages could include a crafted URL that tricks the server into embedding a remote image reference directly. This could allow the attacker to infer the viewer’s IP address and browser fingerprinting information. This vulnerability is fixed in Zulip Server 5.6. Zulip organizations with image and link previews [disabled](https://zulip.com/help/allow-image-link-previews) are not affected. | |||||
| CVE-2016-4427 | 1 Zulip | 1 Zulip | 2024-02-28 | N/A | 7.5 HIGH |
| In zulip before 1.3.12, deactivated users could access messages if SSO was enabled. | |||||
| CVE-2022-31168 | 1 Zulip | 1 Zulip | 2024-02-28 | N/A | 8.8 HIGH |
| Zulip is an open source team chat tool. Due to an incorrect authorization check in Zulip Server 5.4 and earlier, a member of an organization could craft an API call that grants organization administrator privileges to one of their bots. The vulnerability is fixed in Zulip Server 5.5. Members who don’t own any bots, and lack permission to create them, can’t exploit the vulnerability. As a workaround for the vulnerability, an organization administrator can restrict the `Who can create bots` permission to administrators only, and change the ownership of existing bots. | |||||
